So, y'all can sue me for this but I don't care but ... I still don't like the girlfriend. The poor guy can't even have a private thought. As a matter of fact she's abusing her power if you ask me. Though, truth be told, if you have the ability to read minds I guess you might as well use it. Just respect the people you say you care about and don't just be diving into their brain when the feeling hits you.
On the other hand, Mr. Gutter Brain was eating good at the end there. He ALSO wants to correct some boobs but I'm NOT letting him out of the cage after the last debacle.
I went back to read the first couple chapters because I had remembered reading it how she can't really turn it off, it's just that wherever she looks, whatever's in her field of view just dumps info into her brain.
But it seems that was for things like objects in her field of vision, because when she was explaining her powers in chapter 1/2 to the MC, she makes no mention of whether it's a voluntary or involuntary process.
But yeah - it's definitely a problematic power, which explains why she only told the MC because she saw enough of his life story and memories to determine he was a genuinely nice person who wouldn't sell her out to governments/shady organizations for personal gain.
I do think she offers a very effective element to the story of preventing characters from "hiding intentions" in these scenarios that come up, which results in this weird dual-space of "the MC can know everything/one is on the up and up when they approach him", but also "everyone's personal life is exposed to the Fiance character", which is its own, objectively bad can of worms.
So I guess it comes down to what she uses it for, and to what extent she invades the MC's space and life. I could argue that nothing thus far has been seriously problematic or dangerous for him, beyond having a clearly clingy girl who's also willing to let him touch other girls & women to help them because he wants to help others and she wants to help him achieve that.
But in terms of morality her ability is absolutely rife with potential for really bad shit.
